To freeze fresh green beans, trim the bean ends, cut the beans into bite-sized pieces, and blanch and drain them. Place the beans into freezer bags or containers, label the containers with the contents and date, and place in the freezer. Use the green beans within eight to 10 months.
To blanch green beans, begin by bringing a large pot of water to a boil and filling a large bowl with ice water. In small batches, place the green beans into the boiling water. Boil the beans for two to four minutes, depending on their size. Remove the beans from the boiling water, and place them directly into the bowl of ice water. When the beans are cool, remove them from the ice water, and drain them thoroughly.
To freeze green beans without blanching, begin by thoroughly washing the beans and draining them on towels. Cut the green beans to the desired size, and place in freezer bags, making sure to remove as much air as possible. Place the green beans in the coldest part of the freezer, and use them within six to eight weeks. Frozen green beans that are not blanched taste best when used for stir-frying or steaming.
